Although there are many carburettor overhaul kits on the market, one part or rather parts have been conspicuous by their absence.

The pilot air tubing and the thinner tube for the air cut off valve almost always have cracking and splitting and usually are practically cut through by the thin factory wire clips. The clips themselves are invariably rusty. This combination can ruin a nice reconditioning job, not to mention causing running problems.

​

My kits contain five pieces (four for the pilot air tubes and one for the air cut-off valve) of  cut-to-size, silicon rubber fuel tubing and ten bright zinc plated clips. The silicon rubber tubes will last the lifetime of the bike.

The silicon rubber being a bit softer than the OEM tubing, I decided to go with the double wound single wire clip, as being a better solution than the single wound clip that cuts into the rubber. The diagrams below show the reasoning.
